Single-Wavelength 100-Gb/s PAM-4 TDM-PON Achieving Over 32-dB Power Budget Using Simplified and Phase Insensitive Coherent Detection

We experimentally demonstrate the first single-wavelength 100-Gb/s PAM-4 TDM-PON transmission in C-band using simplified and phase-insensitive heterodyne coherent detection. Power budget of over 32 dB is achieved after 20-/40-km fiber transmission.
